Effects of biotic and abiotic factors on forest biomass fractions

Abiotic and biotic elicitors’ effects on secondary metabolites biosynthesis of periwinkle (Catharanthus roseus (Linn.) G. Don)

Based on recent statistical survey, the cancer is the third important factor in Iran mortality. Vinblastine and vincristine alkaloids are dominantly biosynthesized in the aerial parts of periwinkle, broadly applied for cancer treatment. Therefore, over production of these alkaloids by using the biotechnological approaches is inevitable. Since the terpenoid indole alkaloids (TIAS) biosynthesis p...

Effects of biotic and abiotic factors on resistance versus resilience of Douglas fir to drought

Significant increases in tree mortality due to drought-induced physiological stress have been documented worldwide. This trend is likely to continue with increased frequency and severity of extreme drought events in the future. Therefore, understanding the factors that influence variability in drought responses among trees will be critical to predicting ecosystem responses to climate change and...
